hanfuit 645b64fe21 DNF90 服务端与启动器完整源码(含 GM 工具功能增强)
服务端(Go):
- GM 塞背包/带属性装备发放:在线角色推送 op14 增量物品行,背包实时刷新,无需回角色选择界面
- GM 改金币/改等级:去掉在线拒绝,落库后推送 op14 钱包/op37 等级状态,在线实时刷新
- 等级端点统一切换到新版 GMSetCharacterLevel(自带在线刷新)
- 无限/锁死疲劳模式 + 燃烧疲劳:每房间消耗 2 点、打怪与通关经验双倍
- 燃烧疲劳开关时给所有在线角色推送系统提示(op12 mode 0)
- 深渊史诗掉率:GM 全局倍率 + 城镇增益药剂窗口倍率,真实接入掉落结算

启动器(Python/JS):
- 标题栏自绘、窗口 1204x717、禁止拖拽改大小、仅最小化/关闭
- GM 工具:疲劳与燃烧、深渊史诗掉率、拍卖行上架(单一定价对齐)
- 拍卖行上架前端对齐服务端单一价格语义,修复 400 报错

// Package pvf 提供 DNF 类 PVF 资源的启动期内存加载能力。

// 框架只负责把 PVF 文件作为不可变资源装入内存并暴露元信息,不在平台层解释
// DNF 玩法字段;解析、索引和业务校验应放在游戏项目层。
